CA1 — Cicer arietinum

Summary

LOC101498889 (symbol CA1, also known as CaCA1, CaBCA1, SABP3, and BCA1) on chickpea chromosome 2 encodes a beta-type carbonic anhydrase belonging to the Beta_CA_cladeB family, with carbonic anhydrase, peroxidase, salicylic acid binding, calcium ion binding, and mRNA binding activities. This gene is associated with negative regulation of stomatal complex development, response to carbon dioxide, cell redox homeostasis, regulation of stomatal movement, seed germination, defence response to fungi, and response to cold. It has been linked to seed size, salt tolerance, stomatal density and movement, embryo development, immunity, anther cell differentiation, antioxidant response, and reduced fresh weight and photosynthetic pigment content. The protein localises to the chloroplast thylakoid membrane, stromule, endosome, apoplast, and plasmalemma. Studies of related genes in other species link the family to disease resistance, male sterility, water use efficiency, and PSII light-harvesting antenna size.
